PATENT OFFICE PAPER HANDLING JohnQ. Sherman, Dayton, Ohio Application August 7, 1931, Serial 555,811- 18 Claims. (or. 197-133) My invention relates to paper handling and, in particular, to the feeding of a large number of multiple continuous length forms in registration with each other.

It is a special object of my invention to provide a synchronous a large number of multiple continuous length forms in registration with each other, such forms being supplied from a common source and being delivered in a common group of aligned forms.

It is a further object to provide a method of feeding in which-a group of superimposed continuous length forms is supplied, separated into groups, aligned in separate groups, each group being aligned synchronously with the aligning of the other group, and will pass the printing point on the platen in aligned condition in a single group in registration one with the other. It is impossible to feed continuous length forms without having some device to continually adjust them and to take up the discrepancy in alignment between the several .sheets, accumulation of which discrepancies would soon throw the forms out of registration with each other.

, In a pin wheel feed where it is necessary to have the pins enter through holes punched in the printed forms and to go through holes in interleaved carbon paper when used in this manner and traveling in an arc during the radialfeed of the pin bearing bodies (the condition of the some, are always entering the fully engaged and others are leaving the holes), registration can only be obtained at a limited number of copies because of .an overlappingv of forms slightly at the holes due to discrepancies constantly appearing.

I have found in practice that it is possible to feed eight or ten superfolded forms at one time 'with one pin wheel, but, where an increasing number is required, such as fifteen or eighteen possible tosuccessively penetrate so many forms through the holes without mutilation. V

The paper discrepancies themselves are added to due to thefact that the forms are fed circumferentially arolmd the platen, thus causing each superimposed form to travel around a greater circumference.

When alignment is maintained as preferably at or near the writing point, a continual, increasing lack of registration appears the farther you'go around the platen away from the writing point. It is a particular object of my invention, as one embodiment of it, to provide pin wheels which can individualiv, succespin wheel feed adapted to feed at one point,

it also meshes with sively handle eight or ten sheets, and by synchronizing the movement of the two pin wheels, together by suitable gearing and by separating forms into sets for each pin wheel as they proceed from a common supply to the pin wheel, I am enabled to accomplish the foregoing objects.

' I separate the forms into two sets after they leave the printing point, but, before reaching the pin wheel feeds. The separation is accomplished by a guide plate, of which one type is illustrated in the accompanying drawings.

' Referring to the drawings: t

Figure l is an isometric perspective of a typewriter in which the mechanism of my invention has been installed and on which my method is practiced;

Figure 2 is an isometric arator; v

Figure3 is a side elevation of my synchronized pin wheel feed and separator;

Figure 4 is a front elevation of the pin wheel feed;

Figure 5 is a detail view of one form of typewriter friction feeding mechanism, which is adjusted to inoperable position when this invention is applied to the typewriter;

Figure 6 is an end view of the pin wheel feed.

It will be noted that it is desirable that one pin wheel be set either slightly ahead of or apart from' the other so that the pins from one feed do not touch those of another feed. The pin wheels themselves are so synchronized that, while one pin wheel is feeding at a little different position from the other, it is so set as to maintain the forms of the two sets in registration with each other. The forms of the one set originally printed on are divided into two sets.

Referring to the drawings in detail, I desig nates a typewriter having the usual keys 2 actuating the type faces 3 on the type-carrying bars 40 4. In Figure 3 a type face 345 shown at the printi g p int on the typewriter platen 5 around which a plurality of multiple continuous length forms in registration must be fed. This group of forms, as it is supplied around the platen, is designated 6. Mounted on the platen shaft 1' is a master gear 8 meshing with an intermediate pinion 9, which, in turn, engages. the gear I 0 on the shaft I l, which shaft carries the pin wheel drum l2 carrying the pins I 3. v 0

Returning to the gear 9, it will be noted that the gear II which drives the gear I5 on the shaft l6 can'ying the pin wheel drum l1 and the series ofpins IQ.

perspective of my sep- If desired, an eccentrically-arranged drum Q 1 I provide a separator of the form shown in Fig- I ing said forms as a grou 1 end, through which plate construction,

ures 2 and 3 which comprises a pair of arcuate plates 22 and 23 having slots 24 and 25 at either the pins l3 and I8 pass. The strips of paper arranged in groups are separated into those groups and pass over the surfaces of the plates 22 and 23 where they are aligned by the respective sets of pins l3 and I8 after which they maybe brought together into the aligned group of sheets as at 26.

These separator plates 22 and 23 are supported at their respective ends by the arms 21 mounted on the shaft 28 which is suitably supported in theside frame members 29 of the machine. A latch member 30 engages with a shoulder 3! or a shoulder 32 to maintain this separator either in its horizontal or vertical position. A thumb piece 33 is used for actuating the latch which is pivoted at 34 on the side plate 29.

By employing this wedge-shaped, separating it is unnecessary to set one pin wheel ahead of the other because the double plate shape provides clearance enough for the pins of each feeding device to feed in the same relation and clear each other. If a flat plate is used, it is necessary to set one pin wheel slightly ahead of the other and adjust them to feed synchronously to keep the forms of each set in alignment in order to secure a perfectly aligned set of sheets.

It will be understood that a style of pin wheel of the retractible or disappearing pin type may also be used in this combination.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is:
